hey,

i want to telnet somewhere, let say xxx.co.il and be able to see x applictaions. The problem is that i have a proxy inside my lan. all addresses are static ip. so, let say the proxy's internet ip is:163.43.42.15 from outside and 10.0.0.0 inside tha LAN, and the client computer that is inside the lan is 10.0.0.5.
i tried "xhost +" on my computer (10.0.0.5) and "setenv DISPLAY 163.43.42.14::10.0.0.5" on xxx.co.il, after telneting it, but it doesn't seem to work.
is there a way to forward the display to the ip address inside the LAN?
tnx, Or.

You cannot do this with telnet without modifying the settings in your firewall/router. Don't bother - what you attempt to do is *really* dangerous. Telnet is prone to password sniffing, it's only a matter when, not if, your passwords get compromised. Ditto for unencrypted X11 - it's possible for an intruder to actually watch what you are doing on your screen.

ssh with X11 forwarding is the right solution. X11 tunnels through your ssh connection. No netop in his right mind would let unencrypted X11 through, hence everyone is tunneling, which has lots of advantages, for example, that it's actually faster in most cases (ssh compresses the traffic, so on large volumes/slow networks you gain).

If you ssh into that remote machine, you'll find your DISPLAY set to some localhost:12:0 or some such number. Do NOT change that. (If that variable isn't there, it's because X11 forwarding is not the default on your end, you can make it in the config file or temporary use ssh -X.

Hope it helps,

mlp

i new about the ssh option... it just seems a litlle bit complicated, and i'm not sure i could ssh to the host. i guess i have no other choice then....

thanks for the reply,
